Thermo Scientific™ QuEChERS EN 15662 Method Clean-up Kits

Description

• Use Thermo Scientific™ QuEChERS Clean-up Kits to prepare complex sample matrices such as fruits and vegetables for LC-MS or GC-MS analysis of pesticide residues, veterinary drug residues, and toxins using the EN 15662 Method
• Our QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) kits contain pre-packaged, ready-weighed salts, sorbents, and buffers designed to streamline your workflow, provide excellent recoveries for a wide variety of analytes, minimize the potential for error, save time and money, and deliver high-quality, reproducible results
• Thermo Scientific™ QuEChERS EN 15662 Method Clean-Up Kits make sample preparation straight-forward and efficient, enabling you to confidently perform extractions and analyze fruit and vegetable samples for pesticide residues and other contaminants
• Clean-up kits are available in prefilled 2 mL and 15 mL tube formats for the following matrices: general fruits and vegetables, pigmented fruits and vegetables, highly pigmented fruits and vegetables, and fruits and vegetables containing fats and waxes
• What is the purpose of the chemicals used in the EN 15662 Method? Acetonitrile: used to perform single-phase extraction on a sample Anhydrous MgSO4: induces phase separation between water content in sample and acetonitrile layer; removes remaining water from sample NaCl: induces phase separation between water content in sample and acetonitrile layer; removes residual water from sample Trisodium Citrate: buffers the sample to stabilize pH Disodium Citrate Sesquihydrate: buffers the sample to stabilize pH PSA: primary secondary amine, used to remove polar matrix components, citric co-extractives, and free fatty acids, from sample C18: removes fats, sterols, and other non-polar interferences from sample GCB: (graphitized carbon black) removes pigment (not recommended for use with planar pesticides)
